CO₂ MINERALIZATION · NICKEL MINING

Nickel mines have a carbon problem.
The rock underfoot is the fix.

CarbNeutral converts the ultramafic ore already moving through nickel operations into a permanent CO₂ sink — turning a waste-management cost into a source of carbon credits and cleaner metal.

WHAT WE DO

Two ways we cut carbon

A core mineralization technology, and the emissions accounting that makes its impact provable.

01 · TECHNOLOGY DEPLOYMENT

CO₂ mineralization of nickel ore

Ultramafic ore reacts with captured CO₂ in a hydrothermal reactor, locking carbon into stable magnesium carbonate while freeing up nickel for recovery — deployed at your mine site.

02 · EMISSIONS CONSULTING

Scope 1, 2 & 3 accounting

Bespoke emissions calculations for small to mid-sized industry and commercial operators (hospitals, hotels, schools, offices, and more), plus mining companies of any size — for compliance, carbon-offset pricing, or selling credits.

HOW IT WORKS

One reactor, five steps

Serpentine and olivine minerals in ultramafic ore react spontaneously with CO₂ under heat and pressure — locking carbon into stable magnesium carbonate while freeing up nickel for recovery.

Ultramafic ore

Serpentine feedstock

Grinding mill

Ore ground to slurry

Hydrothermal reactor

CO₂ + heat + pressure

Carbonated slurry

Serpentine → magnesite

Froth flotation

WHY IT MATTERS

One process, several returns

Carbon credits

Mineral carbonation qualifies for carbon-offset and credit programs — a revenue line most tailings never generate.

Improved recovery

Recovers metal from low-grade ore that conventional flotation alone leaves behind.

Less tailings

Serpentine tailings convert to useful magnesite, cutting disposal volume and long-term liability.

Regulatory position

Proactive CO₂ sequestration strengthens compliance posture and community standing.

Net-zero pathway

A concrete, ore-based route for mining companies working toward net-zero commitments.

Sellable byproducts

Magnesite and other carbonation outputs leave the site as product, not waste.

PUBLISHED, PEER-REVIEWED

Not a pitch — a published reaction

The chemistry behind CarbNeutral has been validated in the literature, from first model-system results through ore-scale carbonation.

Model-system validation
Preliminary results on model systems, peer-reviewed — the first public disclosure of the reaction chemistry.
Ore-scale carbonation
Carbonation extended from model systems to real ultramafic ore, peer-reviewed.
Process-scale recovery
Peer-reviewed validation of nickel recovery alongside carbonation, at process scale.
Established research foundation
Builds on a broader body of peer-reviewed literature on mineral carbonation in ultramafic mine tailings.
